Dow Introduces New Polyolefin Materials for Steel Pipe Coating to Combat Oil and Gas Pipeline Corrosion

Published on 2010-01-12. Author : SpecialChem

DUBAI, United Arab Emirates (UAE) -- The Dow Chemical Company - a leader in science and technology, has introduced a new top-coat and adhesive polyolefin materials for three-layer steel pipe coating systems.

DOW™ HDPE 12110G, a black high density polyethylene (HDPE) top-coat material, and AMPLIFY™ GR 320 Functional Polymer, a grafted adhesive resin will contribute to the long term corrosion protection of oil and gas pipelines.

The new Dow materials meet stringent performance requirements for coating large diameter steel pipes when used in a three-layer coating system with a fusion bonded epoxy (FBE). External tests have shown that different coating systems using these materials exceed the requirements of the DIN 30670 and other international standards.

"When we entered into this new market segment, we benchmarked our new materials with the current best offering to help ensure that we meet or even exceed their performance and aim to provide the requirements expected by the most demanding customers. As a global leader in Polyethylene, we are commited to support the long term growth of the global Steel Pipe Coating industry," said Katja Wodjereck, Dow's market manager for pipe applications in Europe, the Middle East, India and Africa.

A three-layer steel pipe coating system comprised of DOW™ HDPE 12110G and AMPLIFY™ GR 320, together with an FBE bonded directly on the steel pipe, can help deliver good coating performance for the lifetime of oil and gas pipeline, while also offering excellent processability on conventional pipe coating lines.

As a top-coat material, DOW HDPE 12110G in a three-layer steel pipe coating system offers excellent environmental stress crack resistance (ESCR), excellent physical properties and easy processing. AMPLIFY GR 320, Dow's adhesive, offers excellent adhesion to both the FBE and top-coat layers in a three-layer coating system, in addition to easy processing, mechanical strength at high and low temperatures, good temperature resistance and low water absorption.

The key objective of steel pipe coating is to prevent or minimize the possibility of pipeline corrosion as a result of extreme external conditions, mechanical impacts or degradation by heat or UV irradiation. To help meet this performance requirement, critical parameters for polyolefin materials used in three-layer steel pipe coating systems are excellent adhesion and adhesion retention, durability, crack resistance and long-term stability, together with low levels of built-in stress during the coating process.

About Dow in the Middle East:

Dow has several current and proposed Middle East joint ventures in the UAE, Egypt, Kuwait and Libya as well as in Saudi Arabia, where Saudi Aramco and Dow are in the formation process of a joint venture to build, own and operate a world-scale chemicals and plastics production complex in the Eastern Province. From the opening of its first commercial office in Cairo in the early 1970's to its facility in Jebel Ali in Dubai and its 10-year partnership in Kuwait with EQUATE, Dow has managed to establish a solid presence in the Middle East petrochemicals industry.
